The SI Magwell is the latest addition to the Stan Chen Custom Magwell family. It delivers greatly enhanced reloads, elegant design and maximum durability.
Solid, one piece construction.
Large sculpted funnel for dramatically faster reloads. Through careful CAD design, every last millimeter of available real estate was turned into reload-enhancing surface area.
Designed to very nicely match the beveled magazine wells commonly found on current production 1911s, such as Springfields, Kimbers, Dan Wessons and current Colts (2018 production with fully beveled magazine well) .
Most Colts made prior to 2018, and other frames without full magazine bevels, will require minor blending. (See pictures above). We offer a "Blend Kit" to facilitate this (located under "Accesories").
Eliminates sharp frame corners. Unique funnel profile eliminates sharp edges at front of magazine well opening on the frame. Smoothing of all surfaces on the entire part yields total carry comfort.
Low profile roundbutt. Flowing design. The lines of the entire magwell were designed to flow well with the pistol, giving the bottom of the pistol a cohesive, custom look.
Custom quality checkering. Equaled only by the very best gunsmiths. Perfectly formed diamonds, row after row. Even at 20x magnification. Enhances recoil control.
One-Piece Durability. Precision CNC machined from a solid block of heat treated steel. No joints or screws to work loose, ever.

Perfect Fit!
Took me less than 5 minutes to install and it was a perfect fit for my Springfield Operator. Amazed at how flush it sits. Color was perfect and matched my 1911. Stan Chen posted a YouTube video on how to install it, in case you need it!

Shooter installed magwell
It's rare for me to do a review,but this definitely deserves one. I have a Springfield MC Operator, I first bought an Ed Brown magwell because of good reviews, it was an okay piece no big complaints from me, until I received the Chen SI Magwell ,this thing blows the Ed Brown magwell out of the water. This Chen magwell is bad ass , the fit ,finish, and attention to detail on the machining makes a perfect fit on my Springfield. I was a little bit hesitant on buying the Chen do to price and probability of not liking the look and fit ,and having to deal with a return shipping,but this turned out to not be the case. I love this magwell ,after installing it the price was no longer a factor. I can't speak of fit on any other brand 1911 ,but it was meant to be on a Springfield MC Operator from the way I see it fit . So that I didn't waste the Ed Brown magwell it went to my Philippines made 1911, the MC Operator deserves the Stan Chen SI shooter installed Magwell. Thank you Stan for an Amazing piece of art to complement my MC Operator, and the bag of M&Ms was a nice touch to :) William

Phenomenal
Flawless finishing and the fit was so perfect on my 10mm TRP it didn’t need any fitting. The 25lpi checkering on the back and the round butt are very impressive machining. Highly recommend this magwell!
